2025年3月7日 · Hypoxic-ischemic encephalopathy in adults and older children (i.e. not neonates), also known as global hypoxic-ischemic injury, is seen in many settings and often has devastating neurological sequelae. For a discussion of neonatal hypoxia, refer to neonatal hypoxic-ischemic encephalopathy.

Neonatal hypoxic-ischemic encephalopathy (HIE) is a devastating condition that may result in death or severe neurologic deficits in children. Neuroimaging with cranial ultrasound (US), computed tomography and magnetic resonance imaging are valuable ...

2018年1月9日 · 散发 cjd 患者早期 dwi 示皮层、尾状核、壳核和/或丘脑高信号，其高信号常为对称性，且不符合动脉分布。 dwi 高信号以靠近中线的皮层、岛叶、扣带回及额上回受累多见。 曲棍球征为 cjd 的典型表现，表现为丘脑后部受累，dwi 高信号。

2024年11月24日 · Hypoxic-ischemic encephalopathy is one of the most common causes of cerebral palsy and other severe neurological deficits in children, occurring in 2-9 of every 1000 live births. The encephalopathic neonate may have low Apgar scores at delivery and metabolic acidosis documented in the cord blood.

2016年5月6日 · 众多基础和临床多中心研究证实亚低温治疗对围生期窒息引起的缺氧缺血性脑病（hie）具有明显多靶点非特异性的近期神经保护作用，使其成为 hie 最具潜能的治疗措施之一。近几年来亚低温疗法逐渐从实验室动物模型走向临床试验研究阶段, 从小规模试验走向 ...

1 天前 · Hypoxic Ischemic Encephalopathy (HIE) is a syndrome of acute global brain injury, a severe consequence of cerebral ischemia due to various causes, most common being cardiac arrest, others being carbon monoxide poisoning, hanging, near drowning and strangulation [1].Primary cardiac diseases are the most common causes of cardiac arrest [2, 3].Sudden cardiac deaths contribute to 10.3% of all deaths.

•mimicker of HIE? •Main sequences – T1/ DWI •Timing of imaging – 4 and/or 10 days Summary

缺氧缺血性脑病（HIE）是新生儿常见脑损伤疾病，主要是由孕期母亲疾患、产期窒息、围生期宫内窘迫导致的脑组织中枢神经缺氧缺血损伤，并出现一系列神经系统症状 [ 1 , 2 ] 。 HIE轻症患儿及时进行有效治疗，可不留明显后遗症；但重症、未进行有效治疗的患儿可能会存在癫痫、智力低下、运动障碍等后遗症，对患儿家庭、社会造成严重负担 [ 3 , 4 ] 。 目前，每年约120万HIE新生儿死亡，约100万新生儿因HIE导致永久性神经系统功能障碍 [ 5 ] 。 因此，及时诊断并进行有效 …

2023年2月4日 · Early hyperintensity on diffusion-weighted imaging (DWI): The earliest MRI changes are hyperintensity of signal in basal ganglia and cortex, particularly in the watershed areas. Oedema on DWI looks "bright" because the diffusion of water molecules is restricted in oedematous tissue (they are stuck inside cells and their movement is impeded).

The aim of this study was to explore the value of early assessment of HIE by applying the diffusion-weighted imaging (DWI) in acute (within 72 hours), subacute or chronic stages of HIE in comparison to conventional magnetic resonance imaging (MRI) in clinical practice.
